I agree with what your saying too. I got mine way back in '00 and if the Performer RPM had been out i probably would've ended up with them! But the BSs were available so thats what we went with..my motor was a
street/strip 440...did'nt even port them. So I got into the B1 stuff from then on, put some Originals on my 540...

At first I lkied what i saw with the Indy stuff. But I'm glad i went with B1 now! I still belive Indy has some excellent stuff..the EZ heads were a great idea..and now they have the Predators. Their SB 360-1 series are great too. They have a crap-load of cool stuff...lol..but lousy customer service, IMO.
